Abstract

A multipurpose projectile and a method of making it, said projectile comprising a shell (2) which contains a penetrator (1) and at least one incendiary charge (5) surrounding a portion of the penetrator in front of a well (3) in the bottom of the shell, in which the penetrator has been inserted. The incendiary charge (5) is pressed in approximately over its entire cross section by means of a plunger (14) having an annular pressing surface, and the cavity (12) in which the incendiary charge is situated is cylindrical and has a constant diameter along its entire length, whereby the pressing surface of the plunger substantially covers the entire cavity cross section between the penetrator (1) and the shell (2). The plunger is inserted through the front end of the shell, which is open prior to mounting a nose portion on the shell.
